摘要
航空发动机整机振动历来是发动机研发设计中不可忽视的重要部分,而机匣作为发动机的骨架,它的振动直接反映了发动机整机振动的水平.本文分析了航空发动机机匣动力学问题及故障分类,综述了机匣动力学的国内外发展现状与趋势、问题及解决的办法,并阐述了航空发动机机匣包容性问题的发展现状,最后提出了适合我国航空发动机技术水平的机匣发展设想.
The dynamics of the whole aero-engine system has always been the important part that cannot be neglected in the research and design of the engine, as the framework of the engine, the vibration of the casing directly reflects the level of the whole aero engine vibration. In this paper, an analysis was made on the research of the problems and fault classification of aero-engine casing dynamics, and an overview was made on the research of present situation, development trend, problems and solutions of the domestic and foreign of casing dynamics, which expanded the present situation of the Inclusiveness problems of aero-engine casing dynamics. Finally, some proposals were put forward for the development of the casing dynamics suitable for our country aero-engine technology level.
